Description

Technical Field

[0001] This utility model relates to the field of electronic scales, and in particular to an electronic scale with an adjustable screen. Background Technology

[0002] An electronic scale is an instrument for weighing items. It generally consists of a scale body and a screen. Sometimes, for easier observation, the screen is designed to be adjustable. Typically, the screen is bolted to the scale body. To adjust it, the bolts are loosened, the screen's orientation is adjusted, and then the bolts are tightened again. The problem with this method is that it is relatively cumbersome to operate, requiring the loosening and tightening of bolts for adjustment. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide an electronic scale with a screen that can be easily adjusted by swinging.

[0004] The technical solution adopted by this utility model to solve the problem is: an electronic scale with an adjustable screen, comprising:

[0005] The scale body has a connecting seat and an installation cavity inside the connecting seat. The top of the connecting seat is bent to one side, so that the top surface of the connecting seat forms an arc surface and the top of the installation cavity forms an arc shape. An movable hole through the installation cavity is provided on the arc surface along the bending direction. An arc-shaped support plate located on both sides of the movable hole is fixedly provided in the installation cavity along the bending direction. At least two positioning recesses are arranged on the inner wall of the installation cavity on the side near the arc surface along the bending direction.

[0006] The control panel has a connector at its rear end that is inserted into the mounting cavity through a movable hole. A guide sleeve is fitted on the connector. An extension seat and an extension frame are provided on both sides of the guide sleeve. The extension seat and the extension frame form a channel for a corresponding support frame plate to be accommodated therein. The extension frame abuts against the inner side of the support frame plate. The top of the extension seat has a positioning protrusion that movably engages with the positioning recess. The positioning recess and / or positioning protrusion are rounded so that the positioning protrusion can transition into another positioning recess. The bottom of the connector has a ball bearing cavity. A spring and a ball bearing abutting against the spring are provided in the ball bearing cavity. The ball bearing abuts against the inner wall of the mounting cavity on the side away from the arc surface.

[0007] As a further improvement to the above technical solution, the extension frame is provided with two arc-shaped protrusions for abutting against the inner side of the support frame plate.

[0008] As a further improvement to the above technical solution, two arc-shaped protrusions are respectively arranged at both ends of the extension frame, and the cross-section of the arc-shaped protrusions is circular. The arc-shaped protrusions protrude synchronously on the upper and lower sides of the extension frame.

[0009] As a further improvement to the above technical solution, the extension frame is also arc-shaped, and the degree of bending of the extension frame is less than that of the support frame plate and the mounting cavity.

[0010] As a further improvement to the above technical solution, all the positioning dimples are connected end to end and smoothly transitioned to form a wave shape.

[0011] As a further improvement to the above technical solution, the movable hole extends to the middle of the connecting seat and the positioning recess is also arranged to the middle of the mounting cavity.

[0012] As a further improvement to the above technical solution, the plug-in socket is provided with a through first positioning hole, and the guide sleeve is provided with a through second positioning hole, including a positioning shaft, which is simultaneously inserted into the first positioning hole and the second positioning hole.

[0013] As a further improvement to the above technical solution, the second positioning hole is arranged in the channel.

[0014] As a further improvement to the above technical solution, the upper and lower ends of the two support plates are connected by connecting plates, which are fixed to the mounting cavity by bolts.

[0015] As a further improvement to the above technical solution, a movable shielding plate is provided in the mounting cavity, which is sleeved on the plug-in socket and can move in the mounting cavity to cover the movable hole.

[0016] The beneficial effects of this utility model are as follows: Under normal conditions, the control panel is fixedly positioned on the connecting seat, the plug-in seat is fixedly sleeved with the guide sleeve, and the positioning protrusion on the top of the extension seat is engaged with the positioning recess on the inner wall of the mounting cavity. Under the action of the spring, the ball abuts against the inner wall of the mounting cavity on the side away from the arc surface, thereby forming multi-point contact and positioning to ensure the stability of the control panel. When adjusting the control panel, the user directly moves the control panel in the movable hole. Since both the arc surface and the top of the mounting cavity are arc-shaped, and the support frame plate is located in the groove formed by the extension seat and the extension frame to form a guide, the control panel moves smoothly. During the process, the extension frame abuts against the inner side of the support frame plate to form guidance and assist movement. As the control screen moves along the movable hole, its orientation changes, thus adjusting the orientation of the control screen. During this movement, the positioning protrusions continuously transition into the next positioning recesses. This process requires continuous compression of the spring to allow the beaded ball to enter the beaded ball cavity, providing compensation for the movement space. The compression of the spring and the beaded ball ensures that the positioning protrusions are pressed firmly into the positioning recesses. This serves two purposes: firstly, it fixes the control screen in place when not actively operated; secondly, it creates a tactile feedback during adjustment. With this solution, adjusting the control screen is very simple; it only requires force to move the control screen, making operation extremely convenient. Attached Figure Description

[0028] Reference Figures 1 to 6 An electronic scale with an adjustable screen, comprising:

[0029] The scale body 10 is provided with a connecting seat 20 and a mounting cavity 21 is provided inside the connecting seat 20. The top of the connecting seat 20 is bent to one side, so that the top surface of the connecting seat 20 forms an arc surface and the top of the mounting cavity 21 forms an arc shape. An movable hole 22 is provided on the arc surface along the bending direction, which extends into the mounting cavity 21. An arc-shaped support plate 40 is fixedly provided inside the mounting cavity 21 along the bending direction and located on both sides of the movable hole 22. At least two positioning recesses 211 are arranged on the inner wall of the mounting cavity 21 on the side near the arc surface along the bending direction.

[0030] The control panel 30 has a plug-in seat 31 at its rear end, which is inserted into the mounting cavity 21 through the movable hole 22. A guide sleeve 50 is fitted on the plug-in seat 31. An extension seat 52 and an extension frame 51 are provided on both sides of the guide sleeve 50. The extension seat 52 and the extension frame 51 form a channel 53 for the corresponding side support frame plate 40 to be accommodated therein. The extension frame 51 abuts against the inner side of the support frame plate 40. The top of the extension seat 52 is provided with a positioning protrusion 521 that is movably engaged with the positioning recess 211. The positioning recess and / or positioning protrusion 521 are rounded so that the positioning protrusion 521 can transition into another positioning recess 211. The bottom of the plug-in seat 31 is provided with a ball bearing cavity. A spring and a ball bearing 32 that abuts against the spring are provided in the ball bearing cavity. The ball bearing 32 abuts against the inner wall of the mounting cavity 21 on the side away from the arc surface.

[0031] Under normal conditions, the control panel 30 is fixedly positioned on the connecting seat 20. The plug-in seat 31 is fixedly connected to the guide sleeve 50, and the positioning protrusion 521 on the top of the extension seat 52 is engaged with the positioning recess 211 on the inner wall of the mounting cavity. The ball bearing 32, under the action of the spring, abuts against the inner wall of the mounting cavity 21 on the side away from the arc-shaped surface, thereby forming multi-point contact and positioning to ensure the stability of the control panel 30. When adjusting the control panel 30, the user directly moves the control panel 30 in the movable hole 22. Since the arc-shaped surface and the top of the mounting cavity are both arc-shaped, and the support plate 40 is located in the channel 53 formed by the extension seat 52 and the extension frame 51 to form a guide, the control panel 30 moves smoothly. During the process, the extension frame 51 abuts against the inner side of the support frame plate 40 to form guidance and assist movement. As the control screen 30 moves along the movable hole 22, its orientation changes, thus adjusting the orientation of the control screen 30. During the movement, the positioning protrusion 521 continuously transitions to the next positioning recess 211. In this process, the spring needs to be continuously compressed to allow the dial bead 32 to enter the dial bead cavity to provide compensation for the movement space. The compression of the spring and the dial bead 32 ensures that the positioning protrusion 521 is pressed firmly into the positioning recess 211. This serves two purposes: firstly, it fixes the control screen 30 in place when not actively operated; secondly, it creates a sense of segmentation during adjustment. With this solution, adjusting the control screen 30 is very simple; it only requires force to move the control screen 30, making the operation very convenient.

[0032] In this design, the top of the connector 20 is preferably bent towards the rear along the height direction. In other designs, it can also be adjusted to bend horizontally or in a specific direction, depending on the requirements.

[0033] In this design, the bending angle of the movable hole 22 is preferably 90 degrees, so that the control panel 30 can be adjusted within a range of 90 degrees.

[0034] Further optimization is needed. Considering that surface contact between the extension frame 51 and the inner side of the support plate 40 would increase friction and easily cause jamming, it is preferable that the extension frame 51 has two arc-shaped protrusions 511 for abutting against the inner side of the support plate 40. This creates a double-point contact structure between the extension frame 51 and the inner wall of the support plate 40, making the movement process more stable. Furthermore, it is preferable that the two arc-shaped protrusions 511 are respectively arranged at both ends of the extension frame 51, and the cross-section of the arc-shaped protrusions 511 is circular. The arc-shaped protrusions 511 simultaneously protrude from the upper and lower sides of the extension frame 51. To further prevent the portion of the extension frame 51 excluding the arc-shaped protrusions 511 from contacting the support plate 40 during movement, it is preferable that the extension frame 51 is also arc-shaped, and the degree of curvature of the extension frame 51 is less than that of the support plate 40 and the mounting cavity 21.

[0035] To further optimize the design and make the paragraphs more coherent and prominent, and to allow for more directional angles of the control screen 30, it is preferable to connect all the positioning recesses 211 end to end and make a smooth transition to form a wave shape. This allows for the arrangement of more positioning recesses 211 in the same space, and the number of positioning recesses 211 determines the adjustment level of the directional angle of the control screen 30.

[0036] Further optimization is preferred, with the movable hole 22 extending to the middle of the connecting seat 20 and the positioning recess 211 also arranged in the middle of the mounting cavity 21. This allows for a larger adjustment range, enabling not only angle adjustment within the arc range but also height or horizontal adjustment limited by the connecting seat 20.

[0037] The guide sleeve 50 and the connector 31 can be fixed by interference fit or by adhesive. For ease of assembly and disassembly, the connector 31 preferably has a through first positioning hole 33, and the guide sleeve 50 preferably has a through second positioning hole 54, including a positioning shaft 60, which is simultaneously inserted into the first positioning hole 33 and the second positioning hole 54. Furthermore, the second positioning hole 54 is preferably arranged in the channel 53.

[0038] In this design, the two support plates 40 can be independently fixed in the mounting cavity 21. Considering the convenience of disassembly and assembly, it is preferable that the upper and lower ends of the two support plates 40 are connected by connecting plates 41, which are fixed to the mounting cavity 21 by bolts.

[0039] To further optimize the installation and prevent debris from falling into the mounting cavity 21 along the movable hole 22, a movable shielding plate 70 is preferably provided inside the mounting cavity 21. This shielding plate is fitted onto the connector 31 and can move within the mounting cavity 21 to cover the movable hole 22. Therefore, the movable shielding plate 70 can be formed of a metal sheet. A track is provided within the mounting cavity 21 to accommodate the movable hole 22, allowing the metal sheet to move within the track and always cover the movable hole 22. Alternatively, the movable shielding plate 70 can have a cable chain structure.

[0040] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
